You may illustrate it and the corresponding waveforms.Block Diagram of a power supply: The AC input voltage will go through the transformer which can be a step-up or step-down depending on what is needed. Then, it will pass towards the rectifier bridge that will turn the AC signal to half wave or full wave signal. After the second stage, it is considered as an unfiltered DC voltage because it still has fluctuations. Note that a DC voltage is a straight line. To remove the fluctuations, the signal will be filtered by a capacitor.
From there, the signal will have ripples which we call ripple voltage. It is not completely turned to a DC for it still have small ripples so a regulator is used to completely remove the ripple and produce a stable DC voltage.4.
